RELATED APPLICATIONS

This application claims priority to Chinese patent application number 202220401256.3, filed on Feb. 25, 2022. Chinese patent application number 202220401256.3 is incorporated herein by reference.

FIELD OF THE DISCLOSURE

The present disclosure relates to a press-type telescopic structure of a tent.

BACKGROUND OF THE DISCLOSURE

A tent is a shed which is supported on the ground to shield wind, rain, and sunlight and is used for temporary living. The tent is usually made of canvas material and can be detached and transferred at any time together with a tent support for supporting the canvas. The tent support is an important component part of the tent, and at present, in order to reduce an occupied space after the tent is folded up to make transportation and packing convenient, the tent support in the existing techniques have used telescopic pipes. The telescopic pipes of the tent support comprise an outer tube, an inner tube, and a connecting pipe. One end of the outer tube is inserted in the connecting pipe, and one end of the inner tube extends into the outer tube after passing through the connecting pipe. The one end of the inner tube is fixedly disposed with a guiding slider, and the inner tube and the outer tube are fixedly connected together through a buckle point.

For example, Chinese patent application number 202022422668.9 discloses a telescopic tube of a tent support, comprising an outer tube, an inner tube, and a connecting pipe. A left end of the outer tube is connected with the connecting pipe, and a right end of the inner tube passes through the connecting pipe to extend into the outer tube. A right end of the inner tube is equipped with a guiding slider, and the guiding slider comprises a connecting member and a head portion. The connecting member extends into the right end of the inner tube, and a junction of the connecting member and the head portion defines an abutting surface. The connecting tube is disposed with a pressing member, and a top of the pressing member extends outside of a moving groove. The outer tube and the inner tube respectively comprises a first buckle hole and a second buckle hole, and the first buckle hole and the second buckle hole have an identical size. The pressing member exactly corresponds to the first buckle hole, and an elastic piece is disposed inside of the inner tube. An upper surface of the elastic piece comprises a buckle member, and a top of the buckle member extends out of the second buckle hole and is configured to be inserted into the first buckle hole. An inner side wall of the outer tube comprises at least one protrusion point. When the buckle member is not inserted into the first buckle hole accurately in a telescopic process, the abutting surface of the guiding slider would be in contact with the protrusion point. As can be seen by combining the drawings of Chinese patent application number 202022422668.9, the inner tube and the outer tube both adopt hollow tube structures, and the elastic piece is arranged in the inner tube, so that the inner tube and the outer tube only can adopt metal materials, and the manufacturing cost is very high.

The elastic piece comprises a buckle protrusion configured to be buckled to and matched with the one or more buckle holes after passing through the through hole, and the button is movably disposed on the connecting member and is operatively coupled to the buckle protrusion.

In preferred embodiment, the solid inner tube body is made of fiber material, and the hollow sleeve is made of plastic material.

In preferred embodiment, the solid inner tube body and the hollow sleeve are fixedly connected together by encapsulation.

In preferred embodiment, the connecting member comprises a connecting pipe and a side connecting cover, and one end of the outer tube is disposed in a first side of the connecting pipe. The side connecting cover is disposed in a second side of the connecting pipe, and the solid inner tube body extends into the connecting pipe after passing through the side connecting cover. A locking member is provided to enable the connecting pipe, the side connecting cover, and the outer tube to be fixedly connected together.

In preferred embodiment, the locking member is a rivet, and the connecting pipe, the side connecting cover, and the outer tube respectively comprises a first through hole, a second through hole, and a third through hole, which are coaxially arranged. The rivet is riveted with the first through hole, the second through hole, and the third through hole.

In preferred embodiment, the elastic piece comprises a first straight section, an arc-shaped section, an inclined section, and a second straight section, which are connected in sequence. The first straight section and the second straight section are spaced apart from each other from top to bottom and respectively abut an upper surface and a lower surface of the hollow sleeve, and the buckle protrusion is disposed on the first straight section.

In preferred embodiment, an outer peripheral surface of the hollow sleeve is in clearance fit with an inner wall of the outer tube.

Compared with the existing techniques, the technical solution has the following advantages.

1. The press-type telescopic structure has a more ingenious design, and it is different from the existing techniques in that the inner tube and the outer tube must be hollow structures in the existing techniques. The solid inner tube body is a solid body to ensure enough strength. The hollow sleeve that is located outside of the outer tube is configured for guiding of sliding of the solid inner tube body, and the hollow sleeve is designed to be a hollow structure in which the elastic piece is located, which reduces costs and makes the whole structure more compact.

2. The solid inner tube body is made of fiber material, and the hollow sleeve is made of plastic, which can further reduce the cost.

3. The solid inner tube body is connected to the hollow sleeve by encapsulation. That is, when the hollow sleeve is formed, the solid inner tube body made of fiber material is placed on a specific mold to perform injection molding. An extra connecting and fastening structure is omitted, and a size of the inner tube is reduced.

4. The locking member enables the connecting pipe, the connecting cover, and the outer tube to be fixedly connected together. Therefore, the hollow sleeve will not be separated from the outer tube, thereby ensuring a reliable connection between the inner tube and the outer tube.

5. The locking member is a rivet, and rivet is riveted with the first through hole, the second through hole, and the third through hole, which is simple and reliable.

6. The elastic piece comprises the first straight section, the arc-shaped section, the inclined section, and the second straight section, and the construction of the elastic piece enables a further improvement in elastic deformation thereof.

7. The outer peripheral surface of the hollow sleeve is in clearance fit with the inner wall of the outer tube, which avoids sliding and shaking of the hollow sleeve in the outer tube.

8. The cross-section of the outer tube and the cross-section of the hollow sleeve are D-shaped to achieve a rotation-stopping effect.
